The execution of active checks is delayed until the result is required in the UI. This led to duplicate items in a queue. And the queue was processed multiple times while the UI polls for the service discovery result. This caused a high load on a site.

This werk addresses the performance issues and ensures that active checks are executed only once after a service discovery is finished.
